The Oura Ring 4 is almost as good as the newer model, but $150 cheaper

The previous-generation Oura Ring 4 is on sale for as low as $249 at Amazon , Best Buy , and Target , $100 off the retail price, and the first big discount on the device since July. The price varies a bit by size and color, with most silver and black models in stock at the lowest price between sizes 8 and 13. Best Buy also has an exclusive deep blue “midnight” color in stock for $279. If you’re not sure about your size, you can pick up an Oura Ring 4 sizing kit for $10 at Amazon or Target , which includes $10 in store credit towards an Oura Ring 4 purchase.

The last-gen Oura Ring 4 is a little thicker, but offers much of the same software, sensors, and a wider range of sizes. Where to Buy:

My colleague Victoria Song tested six different smart rings to compare their health and fitness tracking features, and Oura beat them all handily. The Oura Ring 4 improved on its predecessor with more accurate sensors, a slimmer design that leaves the competition in the dust, not to mention frequent software and feature updates. Accessing all of the features requires an active subscription , which is either $5.99 per month or $69.99 per year. The newer Oura Ring 5 is lighter and thinner, but otherwise includes the same sensors and software features as the Oura Ring 4. That makes this previous-generation deal even more appealing,
